![]() ![]() The absolute potential for gallbladder cancer is still quite low, however. The phenomenon of anticipation was once thought to be an artifact, but a biological basis for it has been discovered in a number of genetic disorders. Some data suggest that very large gallstones (greater than 3 cm) also put people at high risk for gallbladder cancer and that these should be removed. Most authorities recommend against performing surgery or medically treating asymptomatic gallstones, except in certain people at high risk for gallbladder cancer. Six percent of men and 9 percent of women will have a gallstone at some point. Furthermore, in medical terms, what is an artifact1. ![]() Should I plan on treatment to prevent trouble, or leave well enough alone?ĭear D.G.: Incidentally found gallstones are common, particularly when performing a test for an unrelated reason in someone with no symptoms referable to the gallbladder. To me, the stone seemed to fill my gallbladder. I do not have any symptoms or digestive issues. Roach: During a routine echocardiogram, my doctor mentioned that I have one very large gallstone. Since these have risks, it’s imperative that the patient discuss with an experienced clinician whether the test is likely to provide information worth taking those risks.ĭear Dr. Particularly medical screenings of cardiac or abdominal regions have to deal with periodic motion arising from cardiac. Other times a more definitive test is needed, such as a cardiac catheterization (angiogram). ![]() When there are conflicting results, as in your case, sometimes the answer is clear from other data (including common sense). In fact, stress tests normally are quite accurate at detecting health and disease. This happens sometimes when there are multiple blockages diffusely in all the blood vessels, since the main thing the physician interpreting the test is looking for is more radiation (meaning more blood flow) in one part of the heart compared with another. In that case, the first stress test was correct that you had heart damage, and the second stress test failed to identify blockages in the heart. Unfortunately, it also is possible that the second test was a false-negative test. These artifacts may cause difficulty in interpretation or suggest a clinical problem. It may be that on the follow-up test, the technician did a better job of placing the camera. The most likely source of the artifact is microscopic metal fragments from the burr, suction tip or other surgical instruments, but other possible causes include hemorrhage or paramagnetic suture material. ![]()
